False. Formation of a compound is usually exothermic because a Noble Gas configuration forms around each atom. Therefore energy is given off during formation, and the atoms in the compound are more stable.
Forming bonds releases energy, whereas breaking bonds requires energy. When bonds are formed, energy is usually released in the form of heat. Conversely, when bonds are broken, energy is absorbed in order to break the chemical bonds.
Natural diamonds are produced very deep in the Earth, under great pressure and heat, and some are brought to the surface of the Earth. The carbon source is graphite rather than coal. They also take a long time to grow.Synthetic diamonds are grown in the 'lab' and thin films of diamond produced this way are used in the semiconductor industry as heat sinks under chips. For diamond has the highest thermal conductivity.For more information, see wikipedia.org under diamond, or carbon, or gemstones.
Ammonia is a covalent compound. It is a compound of two nonmetals, nitrogen and hydrogen, so the difference in electronegativity is not great enough to cause ionic bonding.
CaCl2 is an ionic compound. It is formed by the transfer of electrons from calcium (with a +2 charge) to chlorine (with a -1 charge), resulting in the formation of Ca2+ and Cl- ions, which are held together by electrostatic forces.
Wood is a natural, renewable resource that comes from trees and is commonly used for heating and cooking. Coal is a fossil fuel formed from decomposed plant matter over millions of years, and is primarily used for electricity generation and industrial processes. Coal is denser and more energy-dense than wood, but also more harmful to the environment when burned.
yes
A great energy and light is produced by the supernovas. Therefore, a great number of photons is produced.
No, important is not a compound word.
Most earthquakes are produced by the rapid release of seismic energy stored in rock subjected to great forces. This energy is built up due to tectonic plate movements and is released suddenly when the rock fractures along a fault line.
a large surface area
the energy comes from the strong nuclear force, which is almost unbelievably powerful.
Solar panels are a great renewable resource from the sun. The energy produced is clean and good for the environment.
when the water is flowing over the the dam with high velocity, it acquires great kinetic energy, when this water is used to turn the turbines, this kinetic energy will be converted into electrical energy. so, when the water flows over the dam, hydroelectricity is produced.
Fusion energy is not stored; it is produced through the fusion of atomic nuclei in a controlled environment, such as inside a fusion reactor. The energy produced can be used directly or converted to electricity. Fusion reactions require a constant input of fuel to sustain the process.
Each element has a distinct binding energy - energy which is required to "glue" the individual constituents of an atom (proton, neutron and electrons) together. During nuclear fission, heavier elements decay into lighter elements, thus changing the binding energy of the individual nuclei formed. This minute change releases energy which, when the large number of decays of atoms per second is considered, produces a high quantity of (thermal) energy which is captured by a nuclear fission reactor.

The Great Escarpment is the plateau edge of southern Africa. The Great Escarpment was formed by head water erosion from the rivers.
